<h3 id="（二）为什么要使用-Markdown"><a href="#（二）为什么要使用-Markdown" class="headerlink" title="（二）为什么要使用 Markdown"></a>（二）为什么要使用 Markdown</h3><ul>
<li>格式清晰，读起来很舒服</li>
<li>语法简洁，编写时可以更<strong>专注于内容</strong>而非排版格式  </li>
<li><strong>纯文本</strong>形式，兼容所有的文本编辑器</li>
<li>可导出 HTML、PDF 等常见格式  </li>
</ul>
<h3 id="（三）如何使用-Markdown"><a href="#（三）如何使用-Markdown" class="headerlink" title="（三）如何使用 Markdown"></a>（三）如何使用 Markdown</h3><p>Markdown 的语法非常简单，主要包含以下几个部分：<strong>标题</strong>，<strong>段落</strong>，<strong>列表</strong>，<strong>强调</strong>，<strong>区块引用</strong>，<strong>代码区块</strong>，<strong>行内代码</strong>，<strong>分割线</strong>，<strong>链接</strong>，<strong>自动链接</strong>，<strong>图片</strong>，<strong>反斜杠</strong>，<strong>表格（扩展）</strong>。</p>
<h4 id="1-标题"><a href="#1-标题" class="headerlink" title="1. 标题"></a>1. 标题</h4><p>标题有两种形式，一种形式为在文字下方添加 <code>=====</code> 或 <code>-----</code>，分别表示一级标题和二级标题，如</p>
<figure class="highlight markdown"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br></pre></td><td class="code"><pre><span class="line">一级标题</span><br><span class="line">=====</span><br><span class="line"></span><br><span class="line">二级标题</span><br><span class="line">-----</span><br></pre></td></tr></table></figure>

<blockquote>
<h1 id="一级标题"><a href="#一级标题" class="headerlink" title="一级标题"></a>一级标题</h1><h2 id="二级标题"><a href="#二级标题" class="headerlink" title="二级标题"></a>二级标题</h2></blockquote>
<p>另一种形式在标题前添加 <code>#</code>，添加一个 <code>#</code> 为一级标题，两个为二级标题，最多可至六级标题，如</p>
<figure class="highlight markdown"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br></pre></td><td class="code"><pre><span class="line"><span class="section"># 一级标题</span></span><br><span class="line"><span class="section">## 二级标题</span></span><br><span class="line"><span class="section">### 三级标题</span></span><br><span class="line"><span class="section">#### 四级标题</span></span><br><span class="line"><span class="section">##### 五级标题</span></span><br><span class="line"><span class="section">###### 六级标题</span></span><br></pre></td></tr></table></figure>

<p>段落的开头 <strong>不应该使用空格或者制表符（Tab）缩进</strong>。</p>
<h4 id="3-列表"><a href="#3-列表" class="headerlink" title="3. 列表"></a>3. 列表</h4><p>Markdown 支持无序列表和有序列表。无序列表使用<strong>星号<code>*</code>、加号<code>+</code>或减号<code>-</code>加至少一个空格或制表符（Tab）</strong>作为列表标记，如</p>
<figure class="highlight markdown"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br></pre></td><td class="code"><pre><span class="line"><span class="bullet">* </span>第一项</span><br><span class="line"><span class="bullet">* </span>第二项</span><br><span class="line"><span class="bullet">* </span>第三项</span><br></pre></td></tr></table></figure>
